Comprehensive Guide to Reflective Signage Material

Introduction to Traffic Reflective Vinyl

Traffic reflective vinyl sheeting plays an essential role wherever roads and vehicles converge. You can spot this material in speed limit indicators, stop signs, overhead way-finding signs, and even in parking spaces.

The Grading System for Traffic Reflectives

The quality of reflective vinyl is measured by its ability to reflect light back to its source. For standardization, refer to ASTM D4956 specifications. Reflectivity types are classified using Roman numerals from I to XI. Generally, a higher numeral signifies greater brightness, albeit with a few outliers.

Durability and Usage in Traffic Signs

Engineered for the long haul, the reflective vinyl used in traffic signage starts at a durability level of seven years, with the potential for an even longer lifespan. One key point to note is that this material is best suited for flat surfaces.

Graphic Reflective Vinyl – More Than Just Traffic

Graphic reflective vinyl is evaluated based on two attributes: conformability and durability. Conformability can range from flat surfaces to more complex shapes like corrugations and curves. Some specialized films even adapt to compound curves. The durability of these graphic films is quite similar to their opaque counterparts, ranging from one year to more than seven years.

The Special Case of Conformable Prismatic Films

Conformable prismatic reflective films stand out due to their heightened levels of reflectivity, far surpassing traditional glass-beaded reflective films. These are specifically chosen for emergency vehicles such as police cars, fire engines, and ambulances, where maximum visibility is crucial. While these films offer greater flexibility than their traffic-specific counterparts, they still have limitations when it comes to handling sharp bends and deep recesses—requiring a templating process involving gaps or cut lines.
